Overview and Applications

For high-quality analog color image acquisition at an affordable

price, National Instruments offers the NI 1411 Series, which

consists of PCI and PXI plug-in image acquisition devices that

accept analog video input from standard color or monochrome

cameras. These devices come with easy-to-use image acquisition

driver software. Unlike multimedia “frame grabbers”, the NI 1411

Series features increased image processing throughput, such as

on-the-fly color conversion to HSL and partial image acquisition

with programmable region of interest.

Real-Time Color Conversion

Real-time color conversion is especially useful for high-speed color

matching in industrial or scientific applications, even in varying

illumination. An example of HSL in action is using color to inspect

the presence of an object even though there are shadows and/or

reflections. Lighting variations do not affect the image (hue). Use

the powerful color matching functions in IMAQ Vision to locate

objects quickly and accurately with the onboard HSL conversion.

Easy-to-Use Driver Software

National Instruments NI-IMAQ driver level software offers the

most comprehensive software interface for image acquisition.

NI 1411 Series devices are shipped with the NI-IMAQ image

acquisition

driver

software

and

National

Instruments

Measurement & Automation Explorer for easy configuration of

NTSC and PAL color cameras. Using NI-IMAQ, you can quickly and

easily start your application without having to program at the

register level. You can program your image acquisition application

in LabVIEW, LabWindows/CVI, and Measurement Studio.

In addition, NI-IMAQ controls the NI

1411 digital I/O line.

Performance Gains with

Partial Image Acquisition

The NI 1411 Series includes features

that improve overall image acquisition

and image processing speed. You can

choose to acquire only a portion

of the image using the onboard

programmable ROI feature. You can configure the size of the

acquired image using Measurement & Automation Explorer, or use

the ROI tools in the NI-IMAQ driver software to transfer only a

subset of the image to PC memory for processing. Partial image

scanning results in fewer pixels to process. For example, using

partial image scanning, you can reduce a 640 by 480 image to a

400 by 400 image and increase your processing speed by

operating on 48 percent fewer pixels.

Color Image Acquisition Performance Gains

with Onboard Decimation

Onboard decimation also provides image acquisition and

processing performance gains by allowing onboard scaling or

decimating of the image without using the PC processor. Onboard

decimation scales the image by removing every second, fourth, or

eighth pixel (powers of two only). By reducing the number of pixels

(decimation) on the IMAQ board, the system has fewer pixels to

process with the PC processor. If you remove every other pixel

using onboard decimation, the image size decreases by

50 percent, which speeds up your processing.
